Did you look at the Owon SDS range? The 100Mhz digital storage scope costs Rs30K. Dealer is in Delhi who also sells Metravi ( correct name ?) meters.
You will find the advert in EFY magazine. Lots of reviews about it on the Net.

But simpler analog scopes are available at lower prices . Check EFY magazine for advertisements. They had an issue on oscilloscopes recently.

Take time and study your options. There are many people selling scopes in India today. Better you buy a new one. Old ones may be defective or have hidden problems which are not worth fixing. 100Mhz is good but you can manage with 50/60 Mhz.100Mhz is good to see issues that burnt up your tweeter.

If I were you I'd give preference to a regular analog scope. Your second scope could be a digital one ! You have Scientific scopes , Philips , Aplab etc.

I think there are several analog scopes in the 15 to 20 K range.

Buy several issues of EFY or look for back issues and check out their web site. DON'T buy in a hurry ! COMPARE prices and performance on the web even on international sites. We now have a much better playing field here than we did a few years ago !

That should be a great scope. Hope it's refurbished and calibrated properly.
How much did it cost ? Much better than any locally made scopes.

Trace it back to ISRO ? I heard that lots of great equipment is sold via
the back door from ISRO and many of them are unused ! They just buy to
use up the funds every year. Equipment keeps piling up in the stores !
Cheers.
